WAGON-BRAKE.

Specification of Letters Patent.

Patented April 2 190 7.

Application filed August 7,1906. Serial No. 329,534.

To all whom it may concern.-

Be it known that I, GEORGE F. YOUNG, a citizen of the United States, and a resident of South Kortright, in the county of Delaware and State of New York, have invented a new and Improved VVagon-Brake, of which the following is a full, clear, and exact description.

My invention relatesto brakes adapted to be used on wagons carrying heavy loads, and has for its object to provide a brake which is simple in construction, durable in use, and readily operated under all conditions. This I accomplish by the means illustrated in the accompanying drawings, in which drawings like characters of reference indicate like parts throughout the views, and in which Figure 1 is a plan view of the under side of a forward runninggear of a wagon embodying my invention. Fig. 2 is a vertical longitudinal section taken on the line 1 1 of Fig. 1, showing the parts reversed. Fig. 3 is a side elevation, partly in section, of means for locking the pole in position; and Fig. 4 is a transverse vertical section taken on the line 4 4 of Fig. 3.

As illustrated in the drawings, an axle 1 is mounted upon carrying-wheels 2. Hounds 3 are supported in said axle and braced at their rear ends by means of a cross-bar 5. An auxiliary cross-bar 6, supported on spools 6*, is also secured to the rear ends of the hounds. Parallel glide-bars 13 are connected to the forward ends of the hounds 5 and extend backward and are secured at their rear ends to the axle 1. A brake-beam 7 extends transversely of the rear end of the hounds and is provided with brake-shoes 7, adapted to bear against the tires of the carryingwheels 2. The ends of the brake-beams 7 are supported in loops formed on the ends of the hounds, consisting of upper and lower bars 20 and 21, having a spacing-spool 22 arranged between them. The ends of the brake-beam 7 are connected, by means of rods 8, with levers 9, pivoted upon the axle 1 by means of pivot-pins 9 The inner ends of the levers 9 are pivotally attached to hounds 10, which are connected at their forward ends by means of a pin 11 to a bracket 11, which is secured to a pole 12. The opposite ends of the hounds are formed into loops provided with longitudinal slots 10 adapted to receive the levers 9, which extend through such slots. The pole 12 is provided With a longitudinal slot 12 which extends horizontally through the sides of the pole, adapted to receive a cross-bar 14, secured to the forward. ends of the hounds 3, and the guide-bars 13, connected therewith. A vertical slot 12 is also formed in the pole and is adapted to receive a brake-bolt 18, having a laterally-extending head 18", which is provided with an elongated slot 18 The slot 18 receives an eccentric-pin 15*, secured to a disk 15, which disk is mounted upon the pole 12 in any suitable manner, preferably by means of a pin 15 secured to a bracket 25. A shank 16 extends outward from the disk 15, and its outer end is provided with a weight 16, having a cord 17 connected therewith. A link 24 may be secured to the bracket 25, so as to connect with a king-bolt 23, adapted to secure a draft-tree to the pole. Auxiliary hounds 19, preferably made of bariron, are secured at their forward and rear ends to the hounds 3, with their central portion secured to the under side of the axle 1.

The construction and arrangement of the parts are such that when the brake-bolt 18 is raised so as to clear the transverse bar 14.- the pole 12 is free to be moved backward, longitudinally sliding over the cross-bar 14 by means of the slot 12, formed in the pole. The backward movement of the pole carries with it the hounds 10 and the inner ends of the levers 9, pivoted to such hounds. Such backward movement of the inner ends of the levers 9 draws the connecting-rods 8 for ward, carrying also the brake-beam, so as to bring the brakeshoes 7 a in contact with the tires of the wagon. When, therefore, a loaded wagon having this device applied is going down an inclined grade and the team is held back, the pole 12 is thereby moved backward, with the result already described. The bolt 18 is raised in the vertical slot 12 by means of the cord 17, attached to the weighted end 16 of the lever 16, connected with the disk 15 and provided with the eccentric-pin 15 which engages the slot 18 of the ofiiset head 18 of such bolt. By means of such cord connection the lever may be reversed and the brake-bolt operated by the driver from the top of a load of hay or other high load. The weighted end 16 of the lever 16 holds the eccentric-pin 15 and the brake bolt 18 in any position in which it is set. The brake may berendered inoperative by raising the bolt 18 in its socket, drawing the pole forward, and then depressing the bolt 18 so .as to extend in front of the cross-bar 14.

When so depressed, the lower portion of the offset head 18 of the bolt 18 preferably rests in a groove 12, formed in the upper portion of the pole 12. downward into the slot 12 in front of the cross-bar 1 1, a backward movement of the pole is prevented by the bolt 18 coming in contact with the cross-bar 14, thereby rendering the brakes inoperative. In such case the draft of the pole 12 is applied directly onto the cross-bar 1a. The brake will operate when the bolt 18 is removed from in front of the cross-bar 14, whether this is accom plished by raising the bolt above the horizontal plane of the cross-bar 141, as shown in Fig. 3, or depressed into the slot 12 behind said cross-bar, as shown in Fig. 2. By means of such construction a device is produced which is positive in its operation under all conditions and in all places and is not liable to get out of order. The levers 9 by being mounted upon the under side of the axle 1 on a plane below that of the brakebeam are especially effective in that by means of such construction and arrangement a downward pull is exerted on the rods 8, connecting the brake-beam 7 with such lever.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a forward running gear, of a longitudinally-movable pole, a brake-beam connected therewith, brakeshoes mounted on said beam, a weighted pivoted lever provided with an eccentric-pin, and a bolt movable transversely of said pole, so as to prevent longitudinal movement thereof, substantially as shown and described.

2. The combination with a forward running-gear having hounds connected on their forward ends by a transverse bar, and parallel guide-bars, of a pole provided with a longitudinal slot adapted to engage said bar, hounds mounted on said pole, levers connected at their inner ends to said hounds, connecting-rods pivoted to the outer ends of said levers, a brake-beam secured to the ends of said connecting-rods, brake-shoes mounted on said beam, an eccentric lever, and a When the bolt 18 extends bolt operated by said lever and movable transversely in said pole, substantially as shown and described.

3. The combination with a forward running-gear having hounds mounted upon an axle and connected at their forward ends by means of a transverse bar, of parallel guidebars connected with the forward ends of the hounds and with the axle, auxiliary hounds secured at their central portion to the lower edge of the axle, and at their outer ends to the main hounds, a brake beam, brakeshoes mounted on said beam, connectingrods secured at their rear ends to said brakebeams, and pivoted at their forward ends to transverse levers mounted on the lower edge of the axle in a plane below that of the brakebeam, hounds connected with said levers, a longitudinally-movable pole connected with said hounds, a bolt movable transversely in said pole, and a lever adapted to operate said bolt, substantially as shown and described.

4. The combination with a forward running-gear, of a longitudinally-movable pole, a brake-beam connected therewith, brakeshoes mounted on said beam, a bolt movable transversely of said pole adapted. to prevent longitudinal movement thereof, and a reversible weigl'ited lever connected with said bolt, substantially as shown and described.

5. The combination with a forward running-gear having hounds connected at its forward end by a transverse bar and parallel guide-bars, of a pole provided with a longitudinal slot adapted to engage sald bars and with a vertical aperture communicating with said slot, a brake-beam mounted on said hounds and connected with said pole, brakeshoes mounted on said beam, a bolt movable 1n the vertical aperture of said pole, and a reversible weighted lever connected with said GEORGE F. YOUNG.
